F6R Celeste

F6R celeste team edition

To match the Bianchi bikes FFWD Wheels adjusted the decals to the official Celeste color. A fast and aerodynamic wheel set for flat courses which go just as easy uphill. Wout Poels of Vacansoleil-DCM is climbing often on these!

TECHNOLOGY

Darc

FFWD DARCtm technology is short for ‘Double Arc’ which
refers to the profile of the rim. The revolutionary DARCTM
profile improves aerodynamics dramatically by reducing the
drag. Air has the characteristic to stick to its surface and
by cre¬ating a negative arc section the air will be
compressed more at the positive section. This will increase
the pressure just like on the topside of an airfoil.
Increased pressure results in a faster airflow and less
resistance on the wheel which reduces the drag. The DARCTM
profile is applied to all F4R, F6R and F9R models!

Carbon

We use High-Tensile TC-35 carbon for the majority of the
lay-up. This gives the rim a very high strength with
sufficient stiffness to cope with hard application of the
wheels. So, rather than use a stiffer, but more brittle
carbon type, we chose durability over ultimate stiffness. In
some lay-ups we add some higher modulus sheets to increase
stiffness locally.
We actually use multiple layers of different types of
carbon. Only the outer layer is made from a 3K weave.
Underneath this layer are layers of UDF (Uni-Directional
Fiber) sheets. A mixture of different angles to resemble a
uniform material. Because carbon fiber can handle tension
very well, we have to mix...

ECOM

All rims are molded with a process we call Ecomtm (Equal
Compression). This means that the rims are molded with a
custom-made air bag that has the inner shape of the rim.
This makes sure that the pressure/compression is equal on
the entire inner surface of the rim. Result is a practically
void less rim section and a smooth wall on the inside of the
rim. Without voids, the carbon sheets are completely fused
into one system. The rim structure is much better and you
can make the rim lighter and stronger.
Ecomtm also provides for a smooth inside (no wrinkles!)
which is a great feature and not common for carbon rims.
This is for instance very beneficial for the nipples. Just
imagine how the force of the spoke tension is applied
through the nipple seat onto the rim itself. If the nipple
seat isn't smooth, the transition of the force isn't clean
and optimal. This might cause spoke, nipple or spoke hole
failure in future. FFWD rims are made with Ecomtm which
ensures longevity.
